SQL 2008 64Bit and dBASE III Application

All, I am trying to link my SQL 2008 64bit server to a legacy dBase III program that we have on site using the linked servers in SQL. After much reading on the internet and trial and error I have downloaded the ACE 64bit driver and I am using the following query:

So the syntax is correct? I tried both AND get the same this same error: Cannot initialize the data source object of OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "WINTAM".
OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "WINTAM" returned message "'\\server1\sharefolder\tam' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.". (.Net SqlClient Data Provider)

In your example above, you stated a drive connection. I tried that as well and got the same message. and where does the drive need to be connected on the sql server itself?

You should really test the format d:\folder1\subfldr\ where "d:" represents one single disk drive letter.

To access DBF files on another computer is a little bit problematic task...

It means you have to place DBF files on the same computer where is the SQL Server Service running. The drive letter is C: or D: (etc.) then. The user under which is the SQL Server Service running must have full access to the folder where you placed DBF files and the folder name must be in 8.3 format in connection string.
